TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Apr. 14, 1914.

Application filed December 30, 1912. Serial No. 739,292.

to provide comparatively simple and efficient column selecting means whereby any one of a relatively large number o-f columns may be readily selected by actuating a corresponding column selecting key.

A further object of the invention is to so combine such column selecting mechanism with denominational selecting means that any desired denominational position may be obtained in any selected columnar field.

Another object of my invention is to provide a construction in which the same column stop with wh-ich the column selecting mechanism col-acts to select a column may afterward be engaged by a denominational stop to select a denominational position within the selected columnar field.

A still further object of my invention is to provide means of the character specified which may be readily embodied in existing typewriting machines such as the No. 20 Yost machine, for example, without modifying, or materially modifying, the structural features of said machines as they now exist.

To the above and other ends wh-ich will hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations of devices to be hereinafter set forth and particularly pointed out in the appended claims.

In the accompanying drawings wherein like reference characters designate corre-` sponding parts in the different views, Figure 1 is a fragmentary central fore and aft vertical sectional view of one form of typewriting machine embodying my invention. Fig.

2 is a. diagrammatic plan view showing the I arrangem-ent of the indicator and the column selecting keys. Fig. 3 is a fragmentary plan view of the column stops, the column selecting stops and the denominational stops, together with some of the associated parts.

Fig. 4t is a fragment-ary front elevation with partsin section of the column select-ing stop carrying members and the levers by which they are actuated.

I have shown my invention embodied in the present instance in a No. 2O Yost machine in which the invention may be readily included without modifying, or materially `modifying, the structural features of said machine as they now exist. It should be understood, however, that the invention may be embodied in the nature of an attachment in various styles of typewriting machines.

As shown in the accompanying drawings,

.the frame of the machine comprises side plates 1, a rear cross plate 2, a front cross plate 3 and top plates a and 5. The side vplates support fixed oppositely grooved guide rails 6 which receive anti-friction rollers 7, the latter being likewise received in oppositely grooved guide rails 8 of a carriage truck 9. A platen frame 10 is supported on the truck in the usual manner and carries a rotative platen 11. The carriage is connected in the ordinary manner with a spring drum (notl shown) for movement under the power of the drum from right to left over the top plates of the machine. Depending arms 12 are pivoted at 13 to the truck and carry a feed rack 14C which meshes with a feed pinion 15. This feed pinion is carried by a shaft which extends through a fixed retarder drum 16 and has a sleeve 17 surrounding the shaft near the lower end portion thereof. This sleeve is connected to the shaft by means of a spline 18 which causes the sleeve to rotate with the shaft but enables the sleeve to receive a vertical movement on the sha-ft. A pawl 19 is carried by a yoke-like member 2O which is pivoted on the sleeve 17. The pawl is adapted to engage teeth 21 on the hub of an escapement wheel 22 which surrounds the shaft at the lower end portion thereof. Then the sleeve 17 is in the lowermost or normal position the pawl 19 engages the teeth 21, thus effecting an operative connection between the escapement wheel and shaft to cause the two to rotate together. A second sleeve 23 is slotted at 24 to receive a pin 25 which is connected with a collar 252L of a rotative retarder member contained within the fixed drum 16. The lower end of the sleeve 23 is provided with clutch teeth 26 which are cooperative with corresponding teeth 27 formed in the upper end of the sleeve 17.

It will be understood that an upward movement of the sleeve 17 is effective to disengage the pawl 19V from the escapement wheel and to bring the teet-h 27 into clutching engagement with the teeth 26 so as to operatively connect the escapement wheel shaft with the retarder. This movement of the sleeve 17 is eliected by releasing means wh-ich are constructed as follows: The sleeve 17 has circumferential flanges Q8 forming a circumferential groove between them and in which inwardly projecting pins 29 on a release lever 30 are received. This release lever is bifurcated at its forward end to form a yokelike portion where it carries the pins 29, the lever being pivoted at 31 to a depending post 32 supported by a fixed portion of the machine. This lever is actuated in a manner which will hereinafter appear.

Upwardly and rearwardly extending bracket arms 33 project from the carriage truck and support a column stop bar 34 which upon reference to Fig. l will be seen to be substantially H-shaped in cross section. The upper and lower sides of this column stop bar are groovcd as at 34a to receive bifurcated column stops each designated as a whole by the reference numeral 35. The column stops in the present instance are shown to be sixteen in number and may be adjusted to different positions along the stop bar 34. Each of these column stops is provided with what I term a denominational selecting engaging portion 36. The various engaging port-ions 36 on the diiferent column stops are arranged in a single line transversely of the machine so that they all move in a single path.

A guide comb or plate 37 is fixed to the top p ate 4 and receives upwardly extending arms 38 which form parts of denominational stop levers. These levers are pivoted at 39 to a fixed portion of the machine and have forwardly extending arms 40 which are engaged by key stems 41. These key stems are guided in guide openings in plates 42 and 43 fixed to the frame of the machine. The upper end of each denominational stop lever projects through a slot in the guide comb or plate 37, the projecting portion of each lever forming a denominational stop 44. Each denominational stop lever is connected to one end of a contractile spring 45 which has its opposite end connected to a fixed plate 46 secured to the base of the machine. A universal release baror plate 47 is pivotally mounted at 39 on the same pivot on which the denominational stop levers are mounted. This release plate 47 extends beneath the various denominational stop levers and is adapted to be turned thereby during the depression of a denominational key 4S. An upwardly and rearwardly projecting arm 49 which is connected with the universal bar 47 is connected to one end of a contractile spring 50, the opposite end of which is connected to the plate 46. The arm 49 is likewise connected to an upwardly extending link 51 which in turn is connected by means of a pin 52 and slot 53 to the release lever 30. It will be understood therefore that a depression of the denominational key is effective to move the associated denominational stop 44 into the path of the projections 36 on the column stop 35. This same depression of the key is effective to turn the universal bar 47 thereby effecting an upward movement of the forward end of the release lever 30 to release the pawl 19 from the teeth 21 and throw the clutch teeth 27 into engagement with the teeth 26. -This Vreleases the carriage from control-of the escapement wheel and throws the carriage retarder in-to operation. So far as the denominational mechanism and the carriage releasing means above described are concerned they are somewhat similar to the corresponding mechanisms employed in the No. 20 Yost machine, except that different forms of column stops are employed in that machine.

I prefer to `employ in conjunction with denominational stop mechanism such as that shown the column selectin@` mechanism of my present invention, so that any desired columnar field may first be selected and the denominational position within that field may be obtained by the denominational selecting mechanism. For this purpose each of the column stops 35 is also formed with what I term a column selecting engaging portion or projection 54 which lextends rearwardly from the body portion of the column stop and has a distinctive path of movement with the carriage. There are, in the present instance, sixteen of these projections one on each column stop and each projection has a distinctive path of movement as will be understood from an inspection of Fig. 1. Coperative with the engaging portions 54 are a series of column lselecting stops 55, each of which also has a distinctive path of movement into and out of cooperative relation with the projection 54 on the particular column stop with which it co-acts. Thesecolumn selecting stops 55 are formedas forwardly extending projections on a series of nested yoke-like substantially V-shaped stop carrying members 56. These members extend upwardly in the rear of the machine from a pivot rod 57 which is supported from the base of the machine by brackets 58 and each column selecting stop 55 is located at the apex of its V-shaped stop carrying member. From an inspection of the drawings it will be understood that the column selecting stops, although arranged at different heights to correspond to the arrangement of the engaging projection 54 on the column stops nevertheless have their contact faces all arranged in a single vertical plane which extends fore and aft of the machine. Moreover it will be understood from an inspection of Fig. 8 that the column selecting stops 55 are arranged to the right of the denominational stops 44 at a distance of, say, three letter spaces. It will be seen therefore that these column selectingstops in the movement of the carriage from right to left, are adapted to co-act with their respective column stops before the latter are brought into coperative relation with the denominational stops.

It will be understood that the widely separated bearing points for the stop carrying members 56 on the pivot rod 57 offer an eifectiveresistance to the impact of the carriage when it is arrested through the cooperation of any of the stops 54 with its cooperative column selecting stop 55. AA series of levers 59 are pivoted on the rod 57 and extend forwardly beneath the machine where they connect with key stems 60, each provided with a column selecting key 6l. These key stems like the key stems 41 are guided in openings in the guide plate 42 and in a4 second guide plate 62. There is a lever 59 provided for each of the yoke-like stop carrying members 56 and each lever 59 has an abutment 63 which coperates with a corresponding abutment 64 on one arm of the associated stop carrying member 56 to form a butt or rule joint. A contractile spring 65 connects one arm of each stop carrying member 56 with its associated lever 59. This spring exerts a force to normally maintain the abutments 63 and 64 in contact so that each lever 59 and its associated stop carrying member 56 normally move together as one part. A stop or abutment 66 is fixed to the top plate 4 of the machine and extends into the path of the stop carrying members 56 near the upper end portions thereof. The construction therefore is such that on the depression of a column selecting key 61 the associated stop carrying member will be moved forwardly until arrested by the abutment or stop 66 when the stop carrying member is arrested; but a further movement of the lever 59 may be effected by reason of thespring 65 which connects said lever with the associated stop carrying member in order to effect a release of the carriage as will hereinafter appear. A forward movement of the stop carrying member thus effected brings the associated column selecting stop 55 into the path of a projection 54 on a given one `of the column stops, and with no others since each projection 54 has a distinctive path of movement. derstood therefore that a column selecting stop 55 is coperative with but one of the projections 54 on the column stops and that the carriage will continue to travel, when It will be unreleased, until that particular projection 54 is brought into engagement with the interposed column selecting stop.

ln order to effect a release of the carriage when a column selecting key is depressed l have provided a universal bar 67 which eX- tends beneath the forward end portions of the levers 59 and is adapted to be actuated thereby. This universal bar is connected at its ends to levers 68 which are pivoted at 69 to depending bracket arms 70 carried by the frame of the machine. An arm 71 is connected to the levers 68 and this arm 7l is pivotally connected to an upwardly extending link 72 which in turn is connected at its upper end by a pin 73 and slot 74 to the release lever 30. It will be understood therefore that a depression of any of the column selecting keys is effective to depress the universal bar, thereby elevating the link 72 to effect an upward movement of the forward end of the release lever to release the carriage from control of the escapement wheel and throw the retarder into operation. At this time the pin 52 will move upwardly in the slot 53 of the releasing means connected with and controlled by the universal bar 47 of the denominational stop mechanism. In a like manner an actuation of the denominational stop mechanism will effect an upward movement of the pin 73 in the slot 74 so that the carriage release mechanism may be actuated by either the denominational stop mechanism or by the column selecting mechanism without interference from t-he releasing devices of the other mechanism.

The universal bar 67 is returned to normal position 'by springs 75 each of which is connected at one end to a lever 68 and at its opposite end to the plate 43. The universal bar 67 is limited in its upward movement by one or more stops 76, whereas the downward movement of the universal bar is limited by a stop 77, the stops 76 and 77 being carried by or formed from the plate 62.

Suitable means such as a sleeve 78 and washer 79 may be employed to maintain the stop carrying members 56 properly spaced apart on the pivot rod 57 and to hold them against movement along the rod.

From an inspection of Fig. 2 it will be seen that an indicator designated as a whole by the reference numeral 80 is arranged in the rear of the column selecting keys 61 and may be detachably supported in place by any suitable means. This indicator is preferably divided as shown so as to provide two rows of staggered elongated panels 81 each of which may be inscribed with suitable indices 82 which are alined fore and aft of the machine with one of the column selecting keys 6l. Any suitable indices to indicate the respective columns or the character of items to be written within the columns may be inscribed on the panels in a staggered arrangement such as that shown. It will be seen therefore that while there is but a single row ottabulator keys 6l the indices for these keys are arranged in two rows, the indices in one row being staggered rela-tively to the indices in the other row and the indices for each key being alined therewith fore and aft ot' the machine. This arrangement provides a relatively larger widthwise space in each panel 81 in which with which the particular column selecting` stop co-acts. At the same time the carriage will be released and will move from righty to left until arrested by the cooperation of the (xo-acting stops 54 and 55, thus at a sint gle operation bringing the carriage to the The column stop which co-acts with the projected column selecting stop is arrested to the right of the series of denominational stops as will be= understood from an inspection of Fig. 3 The operator may then depress the desired' denominational k-ey which will interpose the y associated denominational sto-p in the pathk selected columnar field.

of the projection or engaging portion 86 on the same column stop 35 by which an arrest of the carriage was eti'ected through its cooperation with the projected column selecting stop.

riage, thereby bringing the carriage to rest at theproper denominational position within the selected columnar field.

Various changes may be made without departing from the spirit andscope of my invention.
